Purpose
This little known—but handsome—alternative to the Alpine butterfly knot will

also withstand a load that pulls in every direction, but it cannot be tied in the

bight and so is better suited to short lengths of line— such as a lanyard around
the waist for holding tools.

Tying
Arrange the line like a squashed letter M and tie a half knot that encloses the

bight (figures 1–3). Tie a second all-embracing half-knot of opposite handedness
to the first one (figure 4). Tighten the knot (figure 5).

Knot lore

A modified reef or square knot, this contrivance has its origins in the knotting
craft of macramé, which in America is also known as square-knotting.
